l Application filed August 3| 1907. Serial No. 386.949.

` merals and figures of reference marked there- Figure 1 is a vertical longitudinal section, showing the vise connected to a bench. Fig. 2 is a perspective view of the fixed rack plate and guide. Fig. 3 is a view of the actuating shaft showing the retaining collar and the toothed block removed. Fig. 4 is a detached view of the slide and its jaw. Fig. 5 is a transverse section on line 5 5, Fig. 1.

The present invention has relation to vises more especially designed to be attached to a Work bench, but may be used without any Specific reference to a work bench.

Similar numerals of reference indicate corresponding parts in all the figures of the aWin In te accompanying drawing, 1 represents a portion of the top of the work bench. To its top is attached the usual cross bars 2. To the cross bars 2 or their equivalents is attached' the combined rack and guide plate 3,

lwhich plate is preferably provided with the lateral flanges 4, which flanges are provided with the apertures 5, through which apertures the lu boltsl 6 are passed and entered in the cross afs 2 or their equivalents. The rack plateB is rovided with the rack bar 7, which may be ormed integral with the plate 3 or made separate and attached in any convenient and well known manner. The plate 3 is provided with the guide flanges 8, which are substantially of the form shown and are for the purpose of guiding the movable frame 9, which movable frame 1s provided with the clamp-jaw 10, to which clamp jaw 10 may be attached a clamp plate 11 if desired. The movable frame 9 is provided with the flanges 12, which flanges are located in grooves formed by the guide flanges 8. In the movable frame 9 is journaled the shaft 13, to Which shaft is securely attached the operating handle 14. One end of the shaft 13 is passed through the slot 15 and is so located that the shaft can move up and down as hereinafter described. To the shaft 13 is securely attached the cam-head or block 16, against the cam end of which is located the cam end of the cylindrical block 17, which cylindrical block is provided with the upward extended recessed flange 1S, which recessed flange is for the purpose of receiving the short toothed block 19, which teeth are for the purpose of engaging the rack or toothed bar 7 as best illustrated in Fig. 1.

To the outer and opposite end of the shaft from that to which the lever 1/1 is attached is A attached the collar 20 by means of the set screw21 or its equivalent. The collar 20is located against the outer face of the end member of the movable frame and one end of the cam block 16 located against the inner face of the end member of the movable flange by which arrangement there can be no relative or endwise movement between the shaft 13 and the movable frame, but when the parts just above described are properly connected the shaft and all of the parts connected to said shaft move with the movable frames when endwise movementis imparted to said frame.

It will be understood that when the toothed block 19 is out of engagement with the rack bar 7 the movable frame is free to move in its guides and can be 4quickly brought to any desired adjustment within the limits of its movement, but when the toothed block 19 is brought into engagement with the rack bar 7, there can be no endwise movement of the frame .9 together with the different parts carried by the different parts thereby except as hereinafter described. The inner face of the end member of the frame 9 is provided with the flange 22, which flange is so located that the cylindrical portion of the cam head 16 will ride upon the flange 22, but when the cam head 16 is brought into such a position that the cut away ortion of the cam head 16 will come direct y above the flange said cam head 16 will drop or move downward until the straight faced shoulder 23 comes in contact with the top or upper side of the flange 22, and when said cam head 16 together with the shaft 13 and the cylindrical block 17 drops down the toothed block 19 will be disengaged from the rack bar 7. To the shaft 13 is attached the pin 24, .which pin is for the purpose of holding the cylindrical block 17 in proper contact with the cam head or block 16 or in other words causes the cylindrical block to follow or remain in contact at cam ends of all times with the cam end of the block 16.

The operation of my improved vise in use is substantially as follows: Let it be supposed that the movable frame 9 is released so that it is free to slide back and forth or in other words, the toothed block 19 is dise engaged from the rack bar 7, and it is dedesired to clamp a bar or anything else between the fixed end 25 of the work bench proper, or other fixed jaw, and the movable jaw carried by the slidable frame. Said slidable frame together with the jaw is moved toward the end or side of the work bench or fixed jaw or until the movable jaw comes in contact with the bar designed to be clamped after which the shaft is given a partial rotation by the handle 14, which partial rotation elevates the end of the shaft to which the cam head or block is attached and brings the toothed block into engagement with the rack bar 7, and by further rotation of the shaft 13 after the toothed block 19 has been brought into engagement the cam ends of the cam head 16 and the cylindrical block 17 will cause the frame 9 to move endwise, owing to the fact that there can be no relative movement as between the cylindrical block 17 and the toothed rack 7 thereby forcing the frame together with its jaw toward the fixed jaw. This result is accomplished by reason of the shaft 13 being held against end movement with reference to the When it is desired to release the all that is necessary to do is to partially rotate the shaft 13, which partial rotation disengages the toothed bar from the rack bar 7, after which the movablev frame is released and is free to be drawn away from the fixed jaw 25.

It will be understood that the pitch of the cam designed to come in contact with the pin 24 should be the same as the pitch of the cam coming in contact with the cylindrical block 17, by which arrangement the adjacent the cam head 16y and the cylindrical block 17 are in contact with each other at all times. The toothed block 19 is preferably detachably connected to the cam block or head 17 and is so connected for the purpose of easily removing said toothed block for any purpose designed and espeframe 9. bar clamp,

vcially for the purpose of replacing new blocks for worn ones.
